Nowadays, the graduates of medical faculties should be able to use actual complicated technical devices as well as different diagnostical and therapeutical methods based on physical laws and processes. So a good knowledge in physics (including some parts of modern physics) is expected to be mastered by students during their physics education at the faculty. Shortage of hours devoted to physics ...

We discuss some physical aspects of our Liouville approach to non-critical strings, including the emergence of a microscopic arrow of time, effective field theories as classical “pointer” states in theory space, CPT violation and the possible apparent non-conservation of angular momentum. We also review the application of a phenomenological parametrization of this formalism to the neutral kaon ...

Enveloped viruses commonly employ membrane fusion during cell penetration in order to deliver their genetic material across the cell boundary. Large conformational changes in the proteins embedded in the viral membrane play a fundamental role in the membrane fusion process. Despite the tremendously wide variety of viruses that contain membranes, it appears that they all contain membrane fusion ...

Megavoltage electron beams represent an important treatment modality in modern radiotherapy, often providing a unique option in the treatment of superficial tumours (less than 5 cm deep). Electrons have been used in radiotherapy since the early 1950s, first produced by betatrons and then by microtrons and linacs. Modern high energy linacs typically provide, in addition to two megavoltage photon...

If frequent measurements ascertain whether a quantum system is still in its initial state, transitions to other states are hindered and the quantum Zeno effect takes place. However, in its broader formulation, the quantum Zeno effect does not necessarily freeze everything. On the contrary, for frequent projections onto a multidimensional subspace, the system can evolve away from its initial sta...

Physical and dynamic aspects of the electroencephalogram (EEG) were evaluated in 12 schizophrenic patients and 12 matched healthy control subjects by means of two descriptive measures proposed by Hjorth (complexity and mobility) and by a nonlinear measure, dimensional complexity. These measures were compared to power spectra analyses. EEG was recorded from frontal, central, and parietal leads u...

A plasmon generated by a swift charged particle constitutes a coherent excitation about the particle track. We discuss the physics of the plasmon in conden~ed m.atter and its e~ects on ele~tr?n transport in liquid water. Criteria for the existence of the plasmon III a given substance, Its chara~teflsttcs when generated by a swift charged particle, its representation in impact parameter space, a...

Model-based tools have the potential to significantly improve the process of developing novel cyber-physical systems (CPS). In this paper, we consider the question of what language features are needed to model such systems. We use a small, experimental hybrid systems modeling language to show how a number of basic and pervasive aspects of cyber-physical systems can be modeled concisely using th...

Diseases of coronary system and heart are the main reason of deaths in highly civilized population. Then the appropriate diagnostic methods and treating of early disorders are very important for a population health care. As the imaging techniques play a great role in good diagnosis they are intensively used and developed. Among the most commonly used methods is coronary angiography, which invol...

To the metaphors of software engineering and software physics can be added that of software geography. We examine the physical and economic aspects of the Software Glacier (once an innocent bubbling brook, now a vast frozen mass of applications imperceptibly shaping both the Hardware Shelf below and User City above), Quantum Planet (colonization of which could be fruitful if and when it becomes...
